Quote it the way you'd work it
Most estimating tools force every line into quantity × price. Real projects mix billing styles — a fixed permit fee, an hourly engineer, a crew billed by the day. This calculator, and Nummo itself, let each task carry its own method.

Fixed, hourly, or daily
Pick the billing method per task. Durations multiply out automatically and the running total updates as you type.
Private by design
The free calculator above runs entirely on your device — no account, no copy of your quote on anyone's server, including ours.
From quote to invoice
In Nummo, an accepted estimate becomes an invoice in one click — Canadian sales tax, payment links, and your books kept in the background.
